A uniform system for marking X-Ray films with pertinent data. Further, it establishes a technique for manufacturing X-Ray markers which vary only slightly, so that by piggy-backing or stacking, virtually any thickness of marker can be obtained. In addition a method for making a transparent, adherent, and reusable marker is described. The markers are made of brass by a photo-chemical-etching technique and are coated with nickel in order to achieve permanency and contrast against a black plastic background for easy identification and storage.
